Sorry.

Commit c8c68c38b56f ("cpufreq: amd-pstate: initialize core precision boost state") sets per-policy boost flag to false when boost fail. However, this boost flag will be set to reverse value in store_local_boost() and cpufreq_boost_trigger_state() in cpufreq.c. This will cause the per-policy boost flag set to true when fail to set boost. Remove the extra assignment in amd_pstate_set_boost() and keep all operations on per-policy boost flag outside of set_boost() to fix this problem.
